A reporter triggered Usain Bolt to question her being loudly during a post-100m final press conference with the three 100m medallists at the London World Championships.

The reporter expressed her concern regarding the 100m times recorded this year as they were noticeably slower than previous years. She then asked Usain Bolt and Justin Gatlin if they think is it due to “a stronger anti-doping control” why they are much slower this year.
